Making lava lamps

We made lava lamps in summer school today. So cool and so easy!



1. Fill an 8 oz. water bottle about 3/4th full with vegetable oil.
2. Add water but leave a little room at the top.
3. Add 5-10 drops of food coloring.
4. Drop small  pieces of Alka-Seltzer tablets in.
5. When the bubbling stops, put on the cap.
6. Tip the bottle and watch the reactions!
